What browser are you using?

Hey Dan,
I'm getting the 520 errors consistently as well, when clicking on threads. As others mentioned, if I refresh the page it loads as expected. I'm seeing the error across most threads I click on-including this one.

I couldn't reproduce the issue with Firefox on my iPhone.
I also tried turning my adblocker off, which didn't make a difference.

Browser is Mozilla/5.0 (iPhone; CPU iPhone OS 14_7_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.1.2 Mobile/15E148 Safari/604.1
Mobile: true
Tablet: false
Capability: A
Ad blocker: true
Do not track: false
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Edit: I also got the 520 error when I clicked submit on this post.

I'm not surprised: When there's a weird bug, it's almost always Safari.

For those posting reports, are you using an iPhone and Safari? Or are their other variations?

Just happened; first time on the desktop tho:

Browser is Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0
Mobile: false
Tablet: false
Capability: A
Ad blocker: false
Do not track: true
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8

This more often happens on mobile; again Firefox:

Agent

It's happening to me on Firefox on both iPad and iMac.

I've seen other cases where it was only a certain region. Unfortunately, when that's the case, the only solution is time... presumably Cloudflare fixes whatever is broken on their end, despite their error message claiming otherwise.

Clicking the link to this topic from the Recent Forums section of the home page:
Getting HTTP 520 Error Code

Reloading loads properly.

User agent:
Browser is Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.1.2 Safari/605.1.15

Tablet: false
Capability: A
Ad blocker: true
Do not track: false
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

As I mentioned earlier, this error code has appeared for me quite frequently the last several days when I open a topic or post a reply. Browsing the site pages does not appear to cause an error, so far.

Just "got hit" with 520 on Chrome Version 90.0.4430.212 (Official Build) (x86_64) -- macOS 10.14.6 -- Comcrap transport

HB wrote:Is there any particular URL(s) that has "oodles of errors"? For reference, here's my user agent on an iPhone:

It has happened when posting forms:
When logging in
When replying to posts
When sending PM's

It appears that the logins fail but the message posts (forum and PM's) succeed.

I'll see if I can dig any more info out later on my computer but I seem to get this when clicking on a thread for the first time. If I then go back and click the thread again, I still get the error, only refresh solves it.

Using iOS Safari 14 and I haven't updated it in a while.

To me this does not look like a Safari issue, nor an HB issue since it only happens rarely. Feels more like CloudFlare just isn't caching correctly.
